| Abstract(E) | In the contemporary automotive industry, there is an increasing demand to deliver high-quality vehicles to customers within a shorter development period. To shorten the development period, an inverse design approach based on a statistically constrained PCA space incorporating design knowledge is proposed. Under constraints that account for design freedom, shape candidates expected to improve aerodynamic performance are generated efficiently. By enabling direct exploration within feasible design regions, trial-and-error iterations are reduced, and more effective design exploration is facilitated. As a result, the design quality of early-stage aerodynamic performance is improved, contributing to a shorter development period. |
